Viscosan™ - a novel pharmaceutical ingredient

Viscogel AB has developed a unique, highly controlled manufacturing process enabling the production of Viscosan, which is a medical grade chitosan. Viscosan has a highly controlled degree of deacetylation (DD) than standard chitosans, and does not precipitate when injected into the body. It is devoid of endotoxins (<20EU/g), and is non-toxic and biodegradable.


ViscoGel is a patented viscoelastic hydrogel containing 1% Viscosan and 99% water. After the gel is formed it can be mechanically processed to particles of predetermined size. When the gel is exposed to a neutral pH or alkaline conditions it retains its physical form – as a clear transparent gel – instead of forming a white precipitation as occurs with standard chitosan. This gives ViscoGel significantly enhanced biological and physical properties. The particles can be loaded with drugs or biologics and used as a controlled release delivery vehicle.


Viscomulsion is a patented technology based on a ViscoGel containing oil. Viscomulsioncan be used for controlled delivery of hydrophilic and lipophilic compounds and biomolecules in e.g. medicine and cosmetics.
